Presumptive rapid speciation after a founder event in a laboratory population of nereis: allozyme electrophoretic evidence does not support the hypothesis.
TL;DR: The Lab population was already a species different from PI and P2 at the time when it was originally sampled in 1964, and is genetically depauperate, most likely as a consequence of the founder event, but this reduced variability contributes only trivially to the genetic differentiation between the populations.

Models of spliceosomal intron proliferation in the face of widespread ectopic expression.
TL;DR: A speculation on a possible interplay between spliceosomal introns and ectopic expression at the origin of multicellularity is concluded.

Mass Extinctions and Genetic Polymorphism in the “Killer Clam,” Tridacna
TL;DR: It is shown that Tridacna maxima, a plausible modern analog of the lineages that were commonly associated with mass extinctions, is highly polymorphic and heterozygotic, and thus fails to support the depauperate gene-pool hypothesis of mass extinction.

Complete mitochondrial genome of the Amur sculpin Cottus szanaga (Cottoidei: Cottidae).
TL;DR: The low level of sequence divergence detected between the genome of C. szanaga and the GenBank complete mitochondrial genome of the Cherskii's sculpin Cottus czerskii may likely be due to recent divergence, historical hybridization, or presence of a new unrecognized taxonomic unit close to C. czerkii.
